Description

Technical Field

[0001] This utility model relates to the field of oilfield machinery technology, specifically to a lifting ring oscillation device. Background Technology

[0002] The lifting ring deflection device is a key functional component of the traveling block hook in oilfield operations. It is used to adjust the spatial posture of the lifting ring and the lifting clamp to adapt to different wellhead positions or operational requirements. Its core function is to allow the lifting ring (the component connecting the lifting clamp) to deflect within a certain range through angle adjustment, thereby ensuring the alignment and stability of the lifting clamp with the tubing, drill pipe, and other objects being lifted, thus improving operational efficiency and safety.

[0003] Some existing lifting ring deflection devices use dual hydraulic cylinders to achieve angle adjustment. However, dual hydraulic cylinders have the problem of poor synchronization of the hydraulic system. Uneven load or oil pressure fluctuations can easily lead to asynchronous actions, which can cause deflection angle deviation, structural vibration or even equipment damage, affecting the stability and reliability of operation. Utility Model Content

[0004] This utility model provides a lifting ring oscillation device, the purpose of which is to keep the lifting ring in the correct oscillation position.

[0005] To achieve the above objectives, the technical solution of this utility model is as follows:

[0006] A lifting ring deflection device includes: a lifting ring, a fixing frame, a deflection frame, a deflection cylinder, and an adjusting arm;

[0007] The lifting ring is hinged to the side of the floating hook; the fixed frame is fixedly installed on the upper part of the floating hook; one end of the deflection frame is hinged to the fixed frame; the other end of the deflection frame is hinged to one end of the adjusting arm; the other end of the adjusting arm is hinged to the lifting ring; the middle part of the deflection frame is hinged to the fixed frame through a deflection cylinder.

[0008] Furthermore, the two ends of the lifting ring are ring-shaped structures, which are respectively connected to the hanging hook and the lifting clamp.

[0009] Furthermore, the deflection frame is H-shaped overall, symmetrical on both sides, and inclined at one end, with the deflection cylinder pushing the middle part of the deflection frame.

[0010] Furthermore, the deflection includes a crossbar, a first connecting arm, a second connecting arm, a third connecting arm, and a fourth connecting arm;

[0011] The first connecting arm and the third connecting arm are fixedly connected, the second connecting arm and the fourth connecting arm are fixedly connected, the plane on which the first connecting arm and the second connecting arm are located is the first plane, the plane on which the second connecting arm and the fourth connecting arm are located is the second plane, and the first plane and the second plane form an inclination angle;

[0012] The crossbar is fixedly connected at the intersection of the first plane and the second plane.

[0013] Furthermore, a reinforcing plate is provided at the connection point of the two connecting arms.

[0014] Furthermore, one end of the third and fourth connecting arms is provided with several connecting holes for installing the adjusting arm in different positions.

[0015] Furthermore, the adjusting arm is a double-ended screw rod with both positive and negative ends.

[0016] Furthermore, the fixing frame includes a first clamping plate and a second clamping plate, which are fixed to the upper part of the traveling hook by bolts; a first connecting lug is provided at the center of the front part of the first clamping plate for hinged connection of the deflection cylinder; and a second connecting lug is provided on both sides of the front part of the second clamping plate for hinged connection of the deflection frame.

[0017] Furthermore, the adjusting arm is connected to the middle of the lifting ring rod via a U-bolt assembly.

[0018] Furthermore, the U-bolt assembly includes a U-bolt, a connecting plate, and a third connecting lug;

[0019] The U-bolts fix the connecting plate to the lifting ring rod, the third connecting lug is fixedly set on the connecting plate, and the adjusting arm is hinged to the third connecting lug.

[0020] The beneficial effects achieved by this utility model are as follows:

[0021] The single-cylinder drive structure replaces the traditional dual-cylinder system. The deflection cylinder directly pushes the middle of the deflection frame, avoiding the problem of asynchronous action caused by uneven load or oil pressure fluctuations in the dual cylinders. This significantly improves the consistency and stability of the lifting ring deflection angle.

[0022] The deflection frame adopts an H-shaped structure design, and the strength of the connection is enhanced by reinforcing plates, which effectively disperses the thrust of the hydraulic cylinder and reduces the risk of structural deformation.

[0023] The adjusting arm uses a double-ended screw rod in both directions, which can flexibly adjust the length. Combined with the multi-position connection holes at both ends of the deflection frame, it can achieve fine adjustment of the lifting ring posture to adapt to the needs of different wellhead positions.

[0039] like Figures 1-3 As shown, a swinging device for a lifting ring 1 includes: a lifting ring 1, a fixed frame 2, a deflection frame 3, a deflection cylinder 4, and an adjusting arm 5.

[0040] The lifting ring 1 is hinged to the side of the floating hook 6; the fixed frame 2 is fixedly installed on the upper part of the floating hook 6; one end of the deflection frame 3 is hinged to the fixed frame 2; the other end of the deflection frame 3 is hinged to one end of the adjusting arm 5; the other end of the adjusting arm 5 is hinged to the lifting ring 1; the middle part of the deflection frame 3 is hinged to the fixed frame 2 through the deflection cylinder 4.

[0041] The lifting ring 1 connects the traveling block hook and the lifting clamp 7, and is used to suspend and lift downhole tools such as tubing and drill pipe. The lifting ring 1 has ring-shaped structures 11 at both ends; one end is hinged to the side of the traveling block hook 6, and the other end is connected to the lifting clamp 7. Driven by the yaw mechanism, the lifting ring 1 can be adjusted to align the lifting clamp 7 with the wellhead, ensuring the stability of tripping operations.

[0042] The fixed frame 2 serves as the mounting base for the entire yaw mechanism, fixed to the upper part of the swing hook 6, supporting the deflection frame 3 and the hydraulic cylinder. It is secured to the swing hook 6 by bolts via the first clamping plate 21 and the second clamping plate 22, providing stable support. The connecting lugs at its front are used to hinge the deflection cylinder 4 (center) and the deflection frame 3 (both sides), ensuring even force transmission.

[0043] The fixed frame 2 includes a first clamping plate 21 and a second clamping plate 22, which are fixed to the upper part of the hook 6 by bolts; a first connecting lug 211 is provided at the center of the front part of the first clamping plate 21 for hinged connection of the deflection cylinder 4; a second connecting lug 221 is provided on both sides of the front part of the second clamping plate 22 for hinged connection of the deflection frame 3.

[0044] The deflection frame 3 is H-shaped, symmetrical on both sides, and inclined at one end. The deflection cylinder 4 pushes the middle of the deflection frame 3. The deflection mechanism includes a crossbar 31, a first connecting arm 32, a second connecting arm 33, a third connecting arm 34, and a fourth connecting arm 35. The first connecting arm 32 and the third connecting arm 34 are fixedly connected, and the second connecting arm 33 and the fourth connecting arm 35 are fixedly connected. The plane containing the first connecting arm 32 and the second connecting arm 33 is the first plane, and the plane containing the second connecting arm 33 and the fourth connecting arm 35 is the second plane. The first plane and the second plane form an inclination angle. The crossbar 31 is fixedly connected at the intersection of the first plane and the second plane. A reinforcing plate 36 is provided at the connection point of the two connecting arms. One end of the third connecting arm 34 and the fourth connecting arm 35 is provided with several connecting holes 37 for installing the adjusting arm 5 in different positions.

[0045] The deflector frame 3, as the core transmission component, converts the linear motion of the hydraulic cylinder into the yaw motion of the lifting ring 1. Its H-shaped symmetrical design, with connecting arms on both sides hinged to the fixed frame 2 and adjusting arm 5 respectively, ensures force balance and reduces vibration during yaw. The planes of the first connecting arm 32 and the second connecting arm 33 form an inclination angle, optimizing the direction of the hydraulic cylinder thrust and improving transmission efficiency. The crossbar 31, located in the middle, is directly pushed by the hydraulic cylinder, driving the entire deflector frame 3 to rotate, which in turn drives the adjusting arm 5 and the lifting ring 1 to deflect. Multiple sets of connecting holes 37 allow the adjusting arm 5 to be installed in different positions to adapt to different working conditions.

[0046] The deflection cylinder 4 provides power to drive the deflection frame 3, thereby adjusting the angle of the lifting ring 1. One end of the cylinder is hinged to the central connecting lug of the fixed frame 2, and the other end pushes the crossbar 31 of the deflection frame 3. The single-cylinder design avoids the synchronization problem of dual cylinders, ensuring stable and reliable operation. The hydraulic system controls the extension and retraction of the cylinder, causing the deflection frame 3 to rotate around the hinge point, which in turn causes the lifting ring 1 to swing.

[0047] The adjusting arm 5 is a double-ended screw rod 51 with both positive and negative threads, connecting the deflection frame 3 and the lifting ring 1, transmitting motion and fine-tuning the posture of the lifting ring 1. One end is hinged to the connecting arm of the deflection frame 3, and the other end is fixed to the middle of the lifting ring 1 by a U-bolt assembly 52. ​​It adopts a positive and negative thread design, allowing for length adjustment, and is used to calibrate the initial angle of the lifting ring 1 to ensure precise alignment of the lifting clamp 7 with the wellhead.

[0048] The adjusting arm 5 is connected to the middle of the lifting ring 1 rod via a U-bolt assembly 52. ​​The U-bolt 521 grips the lifting ring 1 rod to ensure a stable connection. The U-bolt assembly 52 includes a U-bolt, a connecting plate 522, and a third connecting lug 523; the U-bolt 521 fixes the connecting plate 522 to the lifting ring 1 rod, the third connecting lug 523 is fixedly mounted on the connecting plate 522, and the adjusting arm 5 is hinged to the third connecting lug 523.
